Washington's no-income-tax advantage
Washington State levies no personal income tax, so freelancers and contractors keep their full earnings free of state income tax. Your only income-based obligations are federal: self-employment tax (see our self-employment tax calculator) and federal income tax.
Watch out for the B&O tax
Unlike a true no-tax state, Washington imposes a Business & Occupation (B&O) tax on gross business receipts — not net profit — for many businesses, at low rates that vary by activity. Many small service providers fall under filing thresholds or pay a small amount. It's separate from income tax; check with the Washington Department of Revenue if you have significant receipts.
Quarterly federal taxes
Pay federal quarterly estimates to the IRS if you'll owe $1,000+. There's no state income tax estimate. See how much to set aside for 1099 taxes.
